Looks to me like a typo in the question. It should be asking for the correct option, and as you found that is (i).

Based on the way you drew the arrows, I concur with you that only answer (i) is correct. Is this a computerized test/homework where you are selecting multiple choice? So you were supposed to select the incorrect ones...is that what you did? I have seen these computerized tests coded wit the wrong answer before.
